What is the ballot measure?Proposition 127 would amend the Arizona
Constitution to require private utilities (those that are regulated by the Corporation Commission) to
obtain 50% of their power from renewable resources by 2030. The measure would define renewable
energy to include solar, wind, biomass, certain hydropower, geothermal, and landfill gas energies; it
excludes nuclear fuel.

Background: In 2006, the Arizona Corporation Commission (ACC) approved standards requiring
regulated utilities to obtain 15% of their power from renewable sources by 2025. Those standards
also established reporting requirements for utilities to demonstrate compliance with the standard.
The regulation made Arizona one of 29 states with a percentage-based renewable energy
requirement for utilities. At the end of 2017, regulated utilities (such as APS and TEP) were getting
10% to 13% of their energy from qualifying renewable energy resources.

Provisions:

Would require that private utilities obtain a progressively increasing percentage of their
power from renewable energy resources each year, with an ultimate standard of 50% in 2030
and beyond.

Would also require that private utilities obtain a progressively increasing percentage of their
power from distributed renewable energy resources each year, with an ultimate standard of
10% by 2030 and beyond. This would be energy produced at a customer’s premises (such as
rooftop solar electricity) for their own use, or to sell directly to a utility.

Would track the renewable energy and distributed renewable energy requirements above in
the form of one credit for each kilowatt hour (KWH) of energy produced from renewable
sources. These credits could be transferred to another utility or between utilities, to help
them meet their annual percentage requirement of KWH produced from renewable energy
sources.

Impact:

Models compiled from a study commissioned by the Natural Resources Defense Council,
suggest that Clean Energy for a Healthy Arizona standards would reduce energy costs by $4 billion
between 2020 and 2040 while decreasing pollution and associated health and environmental
hazards. This would occur whether Arizona’s Palo Verde nuclear power plant continued to operate
at its current capacity, or whether it closed.

Arizona Public Service Co. (APS) funded a study by Timothy James, an ASU professor with the W.P.
Carey School of Business, which concluded, in a non-peer-reviewed study using a model not
available for independent analysis, that the state would lose $1.8 billion in state and $1.2 billion in
local taxes, in addition to 7,000 jobs by 2060 under the measure’s standards. This study assumed the
closure of the Palo Verde Nuclear Generating Station in its models.

Arguments For:

According to a study solicited by The Natural Resources Defense Council, electricity bills
would be 3% cheaper in 2030 under the renewable energy future compared with the
currently-planned gas-fired future. The cost of solar power has fallen 86% over the past eight
years, and cost of wind power has fallen 67%. The cost of energy storage has fallen 79% since
2010.

By reducing carbon emissions from power plants that use fossil fuels, we help control
exposure to dangerously unhealthy ground-level ozone.

The American Lung Association has found that Arizona cities and counties have some of the
nation’s dirtiest air, and one in twelve Arizona children suffer from asthma. Prop 127 will
dramatically reduce the rates of asthma attacks, heart disease, lung disease and some
cancers.

We have a moral obligation to help our kids and others inherit a healthy natural environment,
which once gone cannot be replaced.

We need to compete with our neighboring states, which are building clean energy economies
quickly. Over the last five years, solar energy-related jobs grew nine times faster than the
overall economy, but Arizona actually lost solar jobs.

Arguments Against:

This Amendment will increase the cost of doing business in Arizona by increasing the cost of
energy. Wind and solar power are much more expensive than conventional power. The latest
data show wind power is 50% more expensive than conventional power, and solar power is
triple the cost of conventional power.

If approved, these costly and restrictive regulations will drive up housing costs and electricity
prices – doubling the monthly energy bill for the average Arizona household.

Energy policy should not be set by an amendment to the Arizona Constitution because it will
be nearly impossible to modify in the future.

Rural and economically depressed communities, which often obtain their power from electric
distribution cooperatives, will be impacted the most by these increased costs. It is estimated
that electric bills for these consumers may increase by $45 to $65 per month.

The 2030 deadline is much too short for such a major change. A hastened implementation of
the referendum would lead to chaos in providing necessary energy for Arizona.

Palo Verde is the country’s largest supplier of carbon-free energy and employs over 3,000
Arizona workers, but its contributions to Arizona’s energy portfolio would not count toward
the initiative’s proposed mandates.
